Associations Between Placental Corticotropin-Releasing Hormone, Maternal Cortisol, and Birth Outcomes, Based on Placental Histopathology.

Preterm birth remains the leading cause of neonatal morbidity and mortality, with complex biochemical pathways requiring continued understanding and assessment. The objective of this study is to assess the associations between maternal cortisol and placental corticotropin-releasing hormone (placental CRH) concentrations with birth outcomes when stratified by placental histopathology. We conducted an analysis of 112 singleton pregnancies who received betamethasone between 23 and 34 weeks' gestation. Maternal blood and saliva were collected prior to betamethasone administration and samples assayed for plasma cortisol (pCort), salivary cortisol (sCort), and placental CRH levels. Placental findings were characterized as inflammatory, maternal vascular underperfusion (MVU), or no pathology, and compared for the outcomes of placental CRH, pCort, and sCort levels, gestational age at birth (GAB), and birthweight percentiles (BWP). Thirty-six subjects were characterized as inflammatory, 38 as MVU, and 38 without placental abnormalities. Histopathology groups differed significantly on placental CRH levels, GAB, and BWP. Post hoc tests suggested that the MVU group had higher placental CRH than the inflammatory or no pathology groups, and despite delivering earlier than the other two groups, the inflammatory group had infants with significantly higher BWP. No differences existed between groups in terms of mean plasma or sCort levels. Higher placental CRH and pCort levels were associated with earlier GAB in the overall sample, but when split by group, these associations remained significant only among the MVU group. Higher placental CRH was also associated with lower BWP in the overall sample but did not remain significant when split by group. Higher sCort was associated with lower BWP only in the MVU group. There is differentiation of placental CRH, cortisol, and birth outcomes when evaluated by placental histopathology. This highlights the importance of evaluating birth outcomes within the context of placental histopathology.

The Value of Implementing Multidisciplinary Perinatal Care Conference in the Private Practice Setting.

Objective The objective of this study was to estimate the impact of multidisciplinary (Multi-D) perinatal care conference (PCC) implementation in the private practice setting. Methods After the initial 12-month period following implementation of the monthly PCC by private maternal-fetal medicine and neonatology practitioners, conference attendees were asked to completed a modified version of the Attitudes Toward Health Care Teams Scale, involving 19 questions assessing their attitudes and opinions toward Multi-D team care on a five-point Likert's scale. Results Of the 51 average attendees to the PCC, 82.3% completed the survey. A majority of respondents agreed that Multi-D team care resulted in improved care for patients and family, was not overly complex to coordinate, and resulted in significant job satisfaction and improved medical knowledge. Conclusion Multi-D care is an effective approach to the complicated needs of maternal-fetal medicine patients which may lead to improved patient and family outcomes, high provider satisfaction, and can easily be implemented and utilized within a private practice or community hospital setting.

Immediate postpartum glycemic control and risk of surgical site infection.

OBJECTIVE: Nearly one-third of all births in the United States in 2013 were by cesarean delivery, with 6% complicated by diabetes. The purpose of this study was to correlate immediate postoperative hyperglycemia with wound morbidity in diabetic women who underwent cesarean delivery. METHODS: This retrospective case-control study was performed at UC Irvine Health and Miller Women's & Children's Hospital Long Beach between 2009 and 2015. Subjects included women with at least Class B diabetes mellitus who underwent cesarean birth. Fasting and postprandial blood glucose levels (BGL) were recorded daily during postoperative days one through four. Outcomes included abscess formation, cellulitis, wound separation, fascial dehiscence, hospital readmission, secondary wound closure, antibiotic treatment, and a composite of the above. RESULTS: Outcomes were evaluated for 176 subjects. Twenty-nine experienced wound complications. Women readmitted for wound complications and those with composite morbidity experienced significantly higher mean fasting BGL, however, BGL during the immediate postoperative setting were not predictive of wound morbidity. CONCLUSION: In our cohort of diabetic women who underwent cesarean delivery, immediate postoperative hyperglycemia was not associated with wound morbidity.

Patient-prosthesis mismatch in pregnancy.

BACKGROUND: Patient-prosthesis mismatch is a known and severe complication after aortic valve repair in the general population. There is a paucity of literature regarding this condition in pregnancy. CASE: We present the clinical course of a pregnant woman with severe patient-prosthesis mismatch after aortic valve replacement. After extensive workup, the patient underwent aortic valve replacement, enlargement of the aortic root, and placement of a larger prosthetic valve at 21 weeks of gestation. Her postoperative course was complicated by fetal death. CONCLUSION: Cardiopulmonary bypass and aortic valve replacement present a multitude of risks to maternal and fetal health. The obstetrician managing pregnant women with prosthetic heart valves should be aware of the complications that may arise, including patient-prosthesis mismatch.
